The Photos application is now being released to developers, and Apple says it will be available this spring. https://www.apple.com/osx/photos-preview/ Rather than speculate endlessly about it, can we have a thread where people confirm/deny features that Aperture/iPhoto etc users might be interested in? I noted, eg, that re/code had a screen shot that showed an info box that had a field for keywords, and for faces. So that's in. The Verge reported it does not do star ratings or color labels or flags (uses a heart, but they say existing star ratings can be searched for). From David Pogue's preview I gleaned that these deprecated attributes are changed into tags or keywords, hence the ability to search for them. So perhaps adding "blue" is your substitute for a color label, or "one star" or whatever. They say projects get turned into albums, which I'm skeptical about since projects exist in Photos; maybe it's just a definition switch. It does not do geolocation.
